Acute coronary syndrome

Acute coronary syndrome is an umbrella term for a continuum of life-threatening cardiovascular conditions caused by an abrupt reduction in blood flow through the coronary arteries, leading to acute myocardial ischemia or infarction Primarily affecting adults with underlying coronary artery disease, it encompasses unstable angina, non–ST-segment elevation myocardial infarction, and ST-segment elevation myocardial infarction Pathophysiologically, the syndrome is most commonly precipitated by ather...

Primarily affecting adults with underlying coronary artery disease, it encompasses unstable angina, non–ST-segment elevation myocardial infarction, and ST-segment elevation myocardial infarction

Pathophysiologically, the syndrome is most commonly precipitated by atherosclerotic plaque disruption—such as rupture or superficial erosion—followed by platelet activation and thrombosis, leading to partial or total vascular occlusion

Clinically, it presents with ischemic symptoms, classic electrocardiographic alterations, and varying degrees of myocardial necrosis evidenced by elevated cardiac biomarkers such as troponin
